Colt M231, 5.56×45mm NATO (USA, 1980-)
Although it somewhat resembles an M16 (GURPS High-Tech, p. 117) and uses the same magazines, the M231 is actually a bit different both mechanically and in its intended use. It is an extremely rapid-firing weapon with an open-bolt mechanism, designed to be used from the firing ports of the M2 Bradley infantry fighting vehicle. It has a 15.6″ barrel and no stock for ease of handling in the confines of the vehicle. The round hand-guard screws into a connector in the firing port (counts as braced), maintaining a tight seal against nuclear, biological, and chemical weapons. Unfortunately, this makes it impossible to use sights, so the M231 doesn’t have any! Instead, the weapon is meant to be loaded entirely with tracer ammunition and the user ‘walks the burst’ (GURPS Tactical Shooting, p. 16) onto the target.
